HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented J une 8, 1909.

Application led February 6, 1908. Serial No. 414,536.

To all whom it may concern:

Be it known that we, NATHANIEL O. STAMPS and JOSEPH SINGER, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hydrocarb on-Burners, of which the following is a specification.

This invention relates to a hydro-carbon burner of that class which utilize a generating chamber for vaporizing the liquid hydro-carbons which are fed to the burner, and it consists in the combination with such a burner of a starting pan placed beneath the same and of an automatic device to cut off the flow of fuel to the burner and to the starting pan when the starting pan is filled sufliciently.

The invention further consists in the arrangement and construction of the air inlet tubes and mixing tubes so that the vapors are thoroughly mixed with air in the proper proportions for combustion.

We accomplish the above by means of the device described herein and illustrated in the accompanying drawings, in which Figure 1,- is a vertical longitudinal section of the burner in place in the re box of a stove. Fig. 2,- is a horizontal section taken on line 2-2 of Fig. 1. Fig. 3,.-is avertical cross section taken on liney 3-,3 of'Fig. 1. Fig. 4,--is a vertical cross section taken on line 4-4 of Fig. 1.

Referring to the drawings 5 designates a stove fire box of anypreferred construction whose front wall 6 is provided with a door 7, which door is approximately in the position of the usual ash pit door. Openings 8 are cut in wall 6 through which the burner projects into the iire box. The burner comprises a vaporizing chamber 9 which contains a vaporizing pan 10, a mixing and burner cham-V ber 11 and a starting pan 12 being located beneath vaporizing chamber 9. Chamber 9l is contracted as at 13 and passes outwardly through the front wall of the fire box, being provided with a flange 14 on` its outer end. Vaporizing pan 10 is preferably'constructed of a short length of pipe whose forward end is screwed into flange 14 and whose rear or inner end is cut away as shown in Figs. 1 and 2 to form a pan from which the vapors of the liquid hydro-carbons'may escape. Secured to ange 14 is a casting 15 which contains a needle valve 16 controlling the flow `of oil from supply pipe 17 to vaporizing pan 10. This valve is controlled by means of a handle 18,`which may be moved over a dial 19 secured to stufng box 2() of the valve, and the amount of liquid flowing into the vaporizing pan is regulated thereby. A ball valve 21 controlled by a ball stopper 22 is adapted to automatically close the passage between supply pipel 17 and needle valve 16 when left undisturbed. Immediately beneath this ball a vertically movable rod 23 projects upwardly intoV casting 15 through a stufling box 24, the lower end of this rod being pivotally secured to a poivoted lever 25 housed within a oat cham er 26. The other end of pivoted lever 25 is connected to a float 27 which is adapted to be raised or lowered by the increasing or decreasing amount of liquid 28 within chamber 26. Chamber 26 is directly connected to starting pan 12 by a pipe 29 and is provided with an overflow pipe 30 which leads to any convenient receptacle or reservoir. Casting 15 is further provided with a bypass 31 which leads from behind valve 16 and is controlled by a small valve 32 which connects with a small pipe 33 leading to float chamber 26. By opening this valve it will be seen that the liquid from supply pipe 17 may be admitted to the float chamber and to starting pan 12. Both will fll with liquid until the same reaches such a level as to overow through pipe 30. However, when the liquid has reached this level, float 27 will be raised and rod 23 .will thereby be depressed, allowing ball 22 to seat itself and thus cut off the supply of fuel to the whole burner.

Vaporizing chamber 9 is provided with a downwardly opening outlet 40 which leads from a point on its lower side and near its front end within the fire box. This o ening leads to a needle valve41 controlle by a handle 42 which projects out of the fire box as shown in Fig. 1. The entire inner end of the needle valve is surrounded by an air chamber inclosed in a vertical cylindrical casing 43 whose lower end is provided with a pivoted damper 44 adapted to control the entrance of air thereto. This damper may be regulated by opening door 7, but the door is ordinarily kept closed during the operation of the burner, theair which is usedcoming through the grate bars in the usual manner. Immediately under the dischargev point of needle valve `41 a lip V45 is provided on casing 43 to catch any li uid which may ass from the end of the need e valve. A sma l tube 46 leading from the pocket formed by lip 45 is adapted to convey any liquid to starting pan 12. Immediately opposite the discharge point of needle valve 41 casing 43 is provided with an opening into which mixing tube 47 is placed, the vapors from the needle valve being discharged directly into this mixing tube. In passing through the space between the needle valve and the mixing tube the vapors draw after them a supply of air from the air chamber with which they are thoroughly mixed during their passage through the mixing tube. A mixing and. burner chamber 11 is provided on the end of mixing tube 47, this chamber being immediately underneath vaporizing chamber 9 and being provided with outlet burner holes 4S on its sides so that the mixed and combustible vapors are discharged horizontally beneath the vaporizing chamber. Upon being ignited the flame from these vapors does not play directly upon the vaporizing chamber' but passes around it, thus keeping it at a sufficiently high temperature for vaporizing purposes Without any danger of explosion.

From the foregoing it will be seen that we have provided a mechanism which will automatically cut off the fuel supply to the burner if the lire should happen to become extinguished. In this case it will be seen that the vaporizing chamber will immediately become cooled and the liquid hydro-carbons passing into the same will not be vaporized but will overflow from pan 10 and pass down outlet 40 and through valve 41. The liquid will then pass through tube 46 into starting pan 12 and iillthe pan and chamber 26 to the level of overflow 30 or until float 27 has risen sufficiently to alloW ball 22 to close valve 21 and thus shut off the fuel supply to the Whole burner. If any surplus liquid passes into the pan it immediately passes out through overflow 30 and does not flood the burner. Thus if the fire should be extinguished the fuel is not allowed to run out of the burner and Waste. This same operation takes place if dirty fuel is used and the needle valves do not close properly, and if the ball valve should also fail to close for this reason the overflow passes off through pipe 30 to a convenient receptacle. In starting this burner valve 32 is opened to allow starting pan 12 to fill with liquid fuel until valve 21 is closed by the action of float 27. The fuel Within the starting pan is then ignited, valve 32 having been closed. As the fuel in the starting pan is gradually consumed valve 21 opens and alloWs the passage of fuel to valve 16 which may then e opened to supply fuel to the vaporizing chamber. The liquid is then vaporized in the hot chamber and passes through needle valve 41 and out through burner chamber 11 Where it is ignited by the flame from the fuel in pan 12. Thus it Will be seen that it is impossible to supply fuel to the vaporizing chamber before the fuel in the starting pan has been burning for some time so as to thoroughly heat the vaporizing chamber and, prevent all possibility of any fuel fed thereto not being vaporized.

By means of the placement of the vapor discharge within the air feed. chamber so as to be completely surrounded by the same, the mixture of the vapors with the air is more perfectly accomplished and the resultant fiame is a more perfect combustion of the fuel. By the placement and construction of the burner chamber the llame is thrown away from the vaporizing chamber so as to not heat the same to a temperature which is too high and. thus cause explosions besides wasting a large amount of heat unnecessarily upon the vaporizing chamber.
